You don't need to anything, by default routers and switch will not change DSCP value.

Hi Paolo,

So should I configure DSCP just on first Switch or router?

And if you could please tell me the best place where I apply the config?

No need to configure anything, the end devices will set DSCP.

In the switch, remove all qos and similar useless configuarion. That will keep the dsp value inchanged.
